Definitions

  • the primary object of the present invention is to provide an improved horizontal boring machine characterized by a new organization of parts making for a greater degree of precision and accuracy in the work performed and serving to expedite the many operations required in the every day use of a machine of this kind.
  • the invention enables the user to more accurately do the work within a contemplated range and in less time than with horizontal boring 'machines of prior design. 7
  • Another phase of'the invention is the provision in a boring machine of the character described.
  • One phase of the invention is the provision of a horizontal bed and a vertical column in fixed; substantially integral relationship, without relative adjustment. giving a definite basic rigidity for support of the work and the cutter.
  • an arrangement of ways is provided by which the forces of all the cutting actions tend to seat themselves into the V of dovetail ways applied both to the bed and the column, thereby promoting the basic fixed relation contemplated by my invention.
  • Another phase is in the provision of a work table or platen mounted to slide crosswise of the bed and in a plane parallel with the cutter spindle and having power traverse for quickly approaching the work to the cutter and moving it away in response to push button control by the operator in the control position in front of the column.
  • the platen is mounted on a saddle which in turnis reciprocable on the main ways of the bed and is adapted to be moved thereon in the usual feeds and speeds in performance of millingoperations.
  • the new arrangement gives the desired rigidity in support of the platen in all working positions and without overhang of the saddle or the platen incidental to prior designs.
  • FIG. 1 is a front elevational view of a, horizontal boring machine embodying my invention
  • Figs. 2 and 3 are front and side elevational I views, respectively, of said machine with the drive mechanisms and the controls removed, and showing in outline form the relationship of basic parts of my invention
  • Fig. 4 is a top plan view of the parts shown in Figs. 2 and 3;
  • Fig. 5 is a somewhat diagrammatic plan viewof the selective positioning means, above mentioned.
  • the bed and column may be made in one part but for convenience in manufacture they are made separately and rigidly bolted together at the meeting face l3 which preferably extends above the top of the bed, as shown in Fig. 2.
  • the column is provided with vertical ways integral therewith, designated by l4 and l5extending from beneath the bed top to the upper end of the column, on which ways a spindle saddle I6 is mounted for vertical reciprocation thereon.
  • the ways shown are particularly designed for the function of this invention, it being noted that the ways I4 have a V-shape I!
  • the bed I l is provided with ways 2
  • a saddle designated generally by 23 is mounted for lengthwise reciprocation on the bed ways 2
  • the saddle 23 is provided at its top with horizontal ways extending crosswise of the length of the bed and parallel with the cutter spindle 24 which is mounted in the saddle IS.
  • a work table or platen 25 is mounted on the bed saddle ways for reciprocation lengthwise thereon and for positioning thereon in a manner to be presently described.
  • the ways on the top of this saddle comprise flat ways 26 and 21 each located adjacent to one end of the saddle and intermediate ways 28 having a, V-shaped side 29 in which is fitted the correspondingly shaped way portion integral with the platen 25.
  • on the platen engages the opposite end of the saddle ways 28 and L-shaped gibs 32 and 33 fastened to the bed saddle engage the correspondingly shaped ways on the platen to retain
  • the top of the platen may be providedwith T grooves 34 preferably extending lengthwise 0f the platen, for attachment of the work to the face of the platen. It will be observed from Fig. 2 that the horizontal bed as well as the work platen are arranged relatively close to the spindle column so that a substantial range of work may be supported in close relation to the spindle saddle and consequently to the cutter carried by the spindle; and viewing Figs.
  • the work platen may with facility and in response to push button control, or suitable hand control, cause the work platen to be quickly withdrawn to a remote position from the cutter to permit of taking-measurements of the cut as a basis for repositioning the work or the cutter, and for many other purposes familiar to those skilled in this art, and to cause by push button control the platen to be power traversed to a predetermined selected position and to be automatically and rigidly locked in such preselected position to an extremely high degree of accuracy. Since in this type of machine a relatively large proportion of the work may be performed by a power driven spindle having power feed lengthwise or vertically as by travel of the spindle saddle on the column, the advantages of this platen mounting and of its power traverse will be appreciated.
  • My invention is utilized in a machine having conventional or desired power means for imparting lengthwise movement to the bed saddle at different speeds and feeds, as by means of a screw and nut drive, used mainly for milling operations; and conventional or desired power means are employed for moving the spindle saddle vertically on its ways, for feeding the spindle bar axially, and for rotating the bar at different peedsand feeds.
  • a machine having power driven mechanisms responsive to controls as follows: hand crank 4
  • hand lever 43 having three positions, for selecting horizontal saddle feed, vertical spindle saddle feed, or neutral; dial control 44 for quick change of platen saddle feeds; hand wheel 45 for axial adjustment of spindle bar, in coaction with micrometer dial 46 for indicating spindle bar movement; hand lever 41 for spindle bar feed and rapid traverse; hand levers 48 for spindle bar feed changes; hand levers 49 for spindle speed changes; push button 5
  • Hand lever 65 is for locking the spindle saddle to the column; and a similar hand operated lock may b employed to lock the platen saddle to the bed, although the feed screw and I nutoperating between the bed and the platen have provided a power driven means for traversing the platen, an adjustable stop adapted for coaction with a c'amsurface on" the platen for positioning the platen and locking'it against its ways in. a particularly advantageous manner, and a manually operable micrometer control for positioning the stop member, the parts being so constructed and arranged in coaction with the support of the platen and with relation to the cutter spindle that the work piece may be repeatedly removed from a set position and repositioned therein to a degree of precision within one ten-thousandth Of an inch.
  • the platen is propelled by a screw 88 which threads in a nut member 61 which is rigidly fixed in a platen part 68 at the under side of the platen adjacent to the V ways, the screw being journaled on the platen in a manner to be without endwise play with respect thereto and being engaged with the nut member in such manner as to have no lost motion.
  • a supporting bearing for this purpose is shown somewhat diagrammatically at 89 with provision for endwise take-up and this end of the spindle is'driven by reducing gears H from a stub shaft 12 mounted in a, casing which isfixed to the outer end of the platen..
  • An electric motor 18 drives the shaft 12 through means of a sprocket chain 14 and a spring-loadedfriction clutch or slip connection 15 which may be of any suitable or desired construction for transmitting the power traverse torque to the screw 66 and for providing friction slip between the driving and driven members when the platen is brought to final position against the selective. stop member above mentioned.
  • the platen 25 carries a fixed 'abut-' ment face 16, in the nature of a fiat inclined surface adapted to have a camming engagement with a complemental face H which is mounted on the saddle 23 with capacity for adjustment lengthwise of the screw 82. In the present case.
  • the face 16 is a hardened steel insert 18 which is fixed to the platen portion 68 as by having a rigid press fit therein and the face 11 is formed on a slide block 19 mounted on ways 8
  • a screw 82 threads into the-slide block 19 and is suitably journaled 'on the platen so that by rotation of the screw the block I9 may be moved lengthwise on its ways to position its stop surface 11.
  • the screw 82 may be rotated for its selector positioning function by suitable means, such as shaft connections 83-84, mounted on the platen and arranged so that the shaft 84 extends inwardly along one side of the platen to -a control position convenient to the operator.
  • This control is responsive'to the operator who by manipulation of the proper buttons causes the platen to be moved in jogs or runs forward or reverse. These movements of the platen are not for feed purposes but only for withdrawing the work piece from the cutting position to a remote position for measuring the cut, replacement of work piece and cutter, and moving the work piece forwardly to a pre-selected stop position.
  • This control enables the operator to perform the several platen movements with a .minimum of time and attention. The platen may thus be returned to the cutting position, stopped, and locked automatically in response to push button control and will repeat continuously to anfaccuracy of within one ten thousandth of, an inch.
  • Thespindle bar has the usual tool socket as shown in dotted lines in Fig. 2 Face milling cutters may be attached to the main spindle 24, in a manner well known in this art.
  • This main spindle is preferably mounted for rotation in the saddle l8, as in combined radial and end thrust bearing 93 and radial bearing 84, Fig. 2', and the only axial feed movement is to the bar [2.
  • a motor 85 on the column saddle furnishes the driving power for the spindle and bar movements.
  • the bar has suitable quick feeds from .003" to .030" per revolution, a power rapid traverse in either direction, and a slow hand feed movement for accurate setting.
